adding nitrous
i am getting my goodies together for a nitrous install....i am wondering whats best for activating the system...i want to use a wot switch..but do i use one that is triggered by the tps switch or under the pedal????and should i use a msd rpm activated swith with the wot switch......i want the most fool proof system....i am going with a plate between the tb and intake.with nx noids and bottle..most likely 75-100 shot wet...... :yesnod: :confused: :cheers:

Re: adding nitrous (corvette184)
It depends on who you ask about the type of WOT switch to use. Some say they have had problems with the TPS type. I haven't and feel its safer. If you use a switch under the pedal and foreget to turn off traction control (it does happen) then you will continue to spray until you remember to lift your foot after traction control closes the throttle because of wheel spin. Could be a disaster.
Most with a M6 use a window switch. Consider using the new timing controller from RamChargers. It can function as a window switch and retard/advance timing while spraying. Its pretty versital. Do the research. Lots of good info on the forum & good luck. :cheers:

Re: adding nitrous (newberd)
100%. I use a TPS switch and have had no problems. I also use the MSD window switch setup at 3000 on and 6000 off. I have sprayed 150 HP for about 10 months. Prior car set up with 250 HP then turbo and 150Hp. I just finished installing a Vortech system and will leave my nitrous on but will jet for 100 HP and set window switch for 2500 on and 4500 of. By 4500 my boost is up to about 4lbs and don't want any extra power after that up to 7 lbs. :cheers:

Re: adding nitrous (corvette184)
I use all 3 of those in series.
My gas pedal has to be on the floor, and the throttle body valve has to be greater than 98% open, and I have to be in a certian rpm range, before I spray.
You've got a 6 speed so you want the RPM window switch for sure. The WOT limit switch comes with every kit. You're only left whether or not to buy the TPS, so why not buy it and add the extra safety.

Re: adding nitrous (JohnGlenn)
john i think you have my winning ticket...i never thought about using all three...seems like the best bet so far thanks..........any wiring tips???? i havent looked under gas pedal yet but that seems like a wierd place to put a switch...any pointers??? :cool: :cheers: :cheers: :cheers: :cheers: :cheers:

Re: adding nitrous (corvette184)
I only use a WOT switch under the pedal. I had a problem with my TPS so I removed it. You could also put a fuel pressure safety swtich, which I removed because the fuel pressure is always 58 lbs. I also removed my MSD window swtich because I wanted the N20 right off the line. Yes it is safer to have one since it will insure that you are moving when you spray. But the runners are so short on the LS1/6 manifold that its almost impossible to puddle.
IMO less it better when it comes to wiring..
Just my .02

Re: adding nitrous (corvette184)
I have the TPS setup, and I guess I am on of the lucky ones since I haven't had any problem with mine for over 6 month (Knock On Wood :yesnod: ).
I feel it's a bit safer so if you hit the rev limiter, or forget to turn off the traction control, the TPS will shut your system down since your computer will pull the current going to it, where if you have a pedal switch it won't know and continue to spray the nitrous, and could really hurt something.
As fas as a window switch, it's not a bad idea for a M6 if you miss shift, but again if you have a TPS it will shut down the system.
I also have a window switch, and I have it shut the nitrous off right when it shifts (A4), so the nitrous doesn't force the motor to the rev limiter.
Also, I purchased an adujstable pill for my window switch, which ranges from 1000 to 3000rpms. I have it setup at 1000, so there is not delay when I hit it at the track. I was told that as long as your at full throttle, you don't need to have it start at 3000rpm.

Re: adding nitrous (alfromsd)
I've got all my NX parts together now and will be installing mine after I get my car back from having my roll cage installed. I'm going with the mechanical switch at the pedal, window switch, and a progressive controller so I can get some kind of traction. I'm installing their Gemini system that sprays out of the MAF housing. I'll post some pix in a few weeks.

Re: adding nitrous (ICULUKN-C5)
I went with NX's Maximizer. This way I can dial in a 1 second delay with 20% spray continuing on to 100% within another 1 1/2 seconds. I'm told this is the best drag set up for Vette traction issues. We will see.. It cost about $400.00. With all the money I spent on this top of the line Nitrous set up, I should have just saved up and put in a blower!!

Re: adding nitrous (jeffh355)
I also have a Maximizer, and have good success with it.
Nitrous IMO, is alot cheaper then a blower, and people always forget the upkeep on a blower isn't that cheap/easy, especially if its your daily driver.
Also, you can't use a Maximizer with a blower, so I don't think hooking up would be to easy then either.
Let me put it like this, with just some bolt ons, and a 100shot, I was breaking into the lls with street tires.
I could be in the 10s right now, but I need some ET Streets first to make that happen.
Have fun with it!

corvette184,
Here's how I mounted the WOT:

Good Luck.

Re: adding nitrous
Just a word of caution on the progressive type controllers...they work by rapidly pulsing the solenoids. It's not like the nitrous jet orifice changes sizes magically to inject more nitrous over time (which is a great concept, although probably very difficult to ever get to market). Pulsing the solenoids _significantly_ increases the need for rebuild of the solenoids.
I'm not saying they are bad, b/c the fact is they work. :) If you run a real sticky tire, you are less likely to need one, however.
Another way to go (which is what I have used on various cars for years and it works VERY effectively) is to have a manual activation in series with the other good safety activation features (WOT, window switch, etc.).
This way you can go full throttle and have the system armed without necessarily having the nitrous kick on, which would just cause a loss of traction if activated too early. You can vary when the nitrous kicks on based on track or street surface conditions. :)
I have a momentary switch that I fabricated into the stock shifter ****. Looks stealth, and works like a charm.

Re: adding nitrous (corvette184)
I've had the NX TPS for three years with no problems with the switch but I had a wiring problem where it lost contact momentarly and when it remade contact the fuel solenoid would remain closed (the result was 2 nitrous intake backfires and 1 melted piston). Once I figured out what was happening I soldered the TPS connection and have had no problems in the last year. NX could never figure out why the fuel solenoid would not reopen during this pulsing action. I originally purchased their controller and then changed my mind because I didn't like the idea of pulsing the solenoids.
